Problem

The following error message appears:

Quiesced (application-aware) checkpoint of this VM cannot be created.

 

Background

When the “Application aware mode” is enabled, the checkpoint works as follows:

  • NAKIVO Backup & Replication injects a runtime VSS Driver into the VM.
  • NAKIVO Backup & Replication requests the VSS Driver to create a quiesced checkpoint.
  • VSS Driver uses VSS inside a Windows VM to freeze I/O requests of applications inside the OS.
  • If OS quiescing fails to create application-consistent checkpoint, NAKIVO Backup & Replication displays this error.

Possible Cause

The error may be caused by:

  • Credentials
    • Incorrect credentials to the VM
    • Insufficient level of permissions
  • VM access:
    • Incorrect Windows firewall configuration inside the VM
  • VM configuration:
    • Incorrect configuration of the VM OS

Solution

  1. Credentials. Make sure that:
    • You are using the right credentials for the VM.
    • Credentials you are using have administrative permissions.
  2. VM access. Make sure that:
    • Windows firewall allows access to TCP port 9446 from the Director.
  3. VM configuration. 
    • Make sure that the requirements for the Application-aware mode are met.
  • No labels
